AKIBA LOST

AKIBA LOST is a live-action suspense game from IzanagiGames, made with Nippon TV and AX-ON, set in Akihabara and built around a seven-day incident. The story follows Daiki Shinjo, a game creator played by former Kis-My-Ft2 member Hiromitsu Kitayama, investigating the Akiba Kamikakushi case that took six girls 13 years ago. Six women are cast into the incident: maid Aoi Shinjo, underground idol Kokone Nagato, gourmet writer Moe Kurosu, shrine maiden Chihiro Jinbo, cosplayer Wakana Yusa, and streamer Yukimi Kurahashi. Players switch among seven perspectives, and one character's action can resolve another's obstacle.

The game shipped on September 17, 2026 for Nintendo Switch, Nintendo Switch 2, and PlayStation 5. The Steam version slipped on release day over platform-side review, and IzanagiGames announced on October 9 that it will release on October 21. The Steam launch carries a two-week discount raised from 10 percent to 20 percent, 200 added buddy character stills, and dot-art wallpapers for PC and smartphones. Those additions are also planned for the console versions later. The game is priced at 5,500 yen including tax.

Demos ran ahead of release on PS5 on August 20 and on the Switch versions on August 27, with save data carrying to the full game. A demo on Steam opened June 5 and returned for Steam Next Fest from June 16 to 23. The demo covers the morning of Day 1 and ends on a cliffhanger in which Daiki's younger sister Aoi is abducted and a caller warns him to stop developing the game. A playable exhibition ran at Tokyo Game Show 2026 with 30 demo stations running Day 1 PM content.

IzanagiGames published streaming guidelines that allow play up to the Day 6 chapter, with public disclosure from Day 7 onward prohibited. The game was made with a full TV drama series whose six episodes are viewable in-game as DLC. Tsukasa Masuko handles in-game BGM and sound effects, and the soundtrack has 31 tracks, 22 from the drama.
